1. Test method
ASTM D5116-97
- Standard Guide for Small-Scale Environmental Chamber Determinations of Organic Emissions
from Indoor Materials/Products
TEST SAMPLE
- Sample selected for testing is representative of the product manufactured and produced under
typical operating conditions.
TEST PROCEDURE
- The principle of the test is to determine the specific emission rate of VOCs emitted from prepared
specimens of building products.
- The test is conducted in a small-scale environmental chamber at specified constant
conditions of temperature, relative humidity, ventilation rate and product loading factor.

ANALYTICAL METHODS
- TVOC (Total Volatile Organic Compounds): quantified by GC/MS TIC method using toluene as
calibration reference.
- Formaldehyde & acetaldehyde: Volatile aldehydes were quantified by HPLC following ASTM
Method D 5197-97.
- Individual VOCs other than formaldehyde and acetaldehyde were quantified by thermal
desorption GC/MS following EPA Methods TO-1 and TO-17. Compounds are quantified using
multipoint calibrations prepared with pure substances.

LQ |
Not applicable |
"LQ" indicates calculated value is below quantitation base on concentration LOQ (Lower Limit of quantitation). LOQ for TVOC is 20 µgm-3. Most standards and guidelines (Ex: EPA, OSHA, etc) consider 200-500 µgm-3 TVOC an acceptable level in buildings. Levels higher than this may result in irritation to some occupants.
